my favourite pen "Hero" maybe is the best pen in the world! It is made in USA and it was given to me as a gift from my uncle. It helps me write everything i like to put down on paper. when i do my homework, or keep my diary or write a letter to my pen pal, i would always use it. never had i loved a pen so much!
i also take good care of it. once a month, i would clean it and check its parts.
